Figure 68. Actuator Accumulator Charging

ACTUATOR ACCUMULATOR CHARGING

CAUTION

Ensure regulator valve is fully backed off to relieve tension in

diaphragm. Failure to comply may result in damage to equipment.

NOTE

Have suitable container ready to catch oil.

Adjust regulator valve (Figure 68, item 2) on nitrogen tank (Figure 68, item 3) to

800--900 psi (5,516--6,206 kPa).

Open shutoff valve (Figure 68, item 4). Read pressure measuring device (Figure 68,

item 5).

When pressure reaches 800--900 psi (5,516--6,206 kPa), close shutoff valve (Figure 68,

item 4), nitrogen tank valve (Figure 68, item 1), and accumulator charge valve

(Figure 68, item 10).

Wait 15 minutes and open accumulator charge valve (Figure 68, item 10). Read

pressure measuring device (Figure 68, item 5) to determine if accumulator can retain the

charge.

Tighten nut (Figure 68, item 7) on charge valve (Figure 68, item 10). Close nitrogen tank valve

(Figure 68, item 1). Back off regulator valve (Figure 68, item 2), open bleed valve (Figure 68,

item 11), and bleed hose pressure to 0 psi. Remove adapter valve (Figure 68, item 9) from

charge valve (Figure 68, item 10). Remove pressure measuring device (Figure 68, item 5) from

bleed valve (Figure 68, item 11) on charging harness. Install charge valve cap (Figure 68,

item 8) on actuator accumulator (Figure 68, item 6).
